PIX causing problems with TLS esmtp session

Unanswered Question
Feb 27th, 2009

There is one particular outside mail server we're having trouble sending to. Basically, our server (Groupwise) does an EHLO, and the other server offers STARTTLS. Our server sends a STARTTLS, sends a few bytes of encrypted data, and then the other server sends a RST.

If we try a test server outside the PIX, everything is fine.

I've looked at "no fixup protocol smtp 25" and "no inspect esmtp" and those already seem to be in place.

Could the pix be doing something with the certificate? Could esmtp inspection still be on?


I have this problem too.

You may try bypassing the spam server just to make sure that it is not theone causing to filter out few esmtp commands.
